BACKGROUND OF THE INVENTION

The activity of cells can be regulated by external signals thatstimulate or inhibit intracellular events. The process by whichstimulatory or inhibitory signals are transmitted into and within a cellto elicit an intracellular response is referred to as signaltransduction. Over the past decades, cascades of signal transductionevents have been elucidated and found to play a central role in avariety of biological responses. Defects in various components of signaltransduction pathways have been found to account for a vast number ofdiseases, including numerous forms of cancer, inflammatory disorders,metabolic disorders, vascular and neuronal diseases (Gaestel et al.Current Medicinal Chemistry (2007) 14:2214-2234).

Kinases represent a class of important signaling molecules. Kinases cangenerally be classified into protein kinases and lipid kinases, andcertain kinases exhibit dual specificities. Protein kinases are enzymesthat phosphorylate other proteins and/or themselves (i.e.,autophosphorylation). Protein kinases can be generally classified intothree major groups based upon their substrate utilization: tyrosinekinases which predominantly phosphorylate substrates on tyrosineresidues (e.g., erb2, PDGF receptor, EGF receptor, VEGF receptor, src,abl), serine/threonine kinases which predominantly phosphorylatesubstrates on serine and/or threonine residues (e.g., mTorC1, mTorC2,ATM, ATR, DNA-PK, Akt), and dual-specificity kinases which phosphorylatesubstrates on tyrosine, serine and/or threonine residues.

Lipid kinases are enzymes that catalyze the phosphorylation of lipids.These enzymes, and the resulting phosphorylated lipids and lipid-derivedbiologically active organic molecules, play a role in many differentphysiological processes, including cell proliferation, migration,adhesion, and differentiation. Certain lipid kinases are membraneassociated and they catalyze the phosphorylation of lipids contained inor associated with cell membranes. Examples of such enzymes includephosphoinositide(s) kinases (such as PI3-kinases, PI4-Kinases),diacylglycerol kinases, and sphingosine kinases.

The phosphoinositide 3-kinases (PI3Ks) signaling pathway is one of themost highly mutated systems in human cancers. PI3K signaling is also akey factor in many other diseases in humans. PI3K signaling is involvedin many disease states including allergic contact dermatitis, rheumatoidarthritis, osteoarthritis, inflammatory bowel diseases, chronicobstructive pulmonary disorder, psoriasis, multiple sclerosis, asthma,disorders related to diabetic complications, and inflammatorycomplications of the cardiovascular system such as acute coronarysyndrome.

PI3Ks are members of a unique and conserved family of intracellularlipid kinases that phosphorylate the 3′ —OH group onphosphatidylinositols or phosphoinositides. The PI3K family comprises 15kinases with distinct substrate specificities, expression patterns, andmodes of regulation (Katso et al., 2001). The class I PI3Ks (p110α,p110β, p110δ, and p110γ) are typically activated by tyrosine kinases orG-protein coupled receptors to generate PIP3, which engages downstreameffectors such as those in the Akt/PDK1 pathway, mTOR, the Tec familykinases, and the Rho family GTPases. The class II and III PI3-Ks play akey role in intracellular trafficking through the synthesis of PI(3)Pand PI(3,4)P2. The PIKKs are protein kinases that control cell growth(mTORC1) or monitor genomic integrity (ATM, ATR, DNA-PK, and hSmg-1).

The delta (6) isoform of class I PI3K has been implicated, inparticular, in a number of diseases and biological processes. PI3K δ isexpressed primarily in hematopoietic cells including leukocytes such asT-cells, dendritic cells, neutrophils, mast cells, B-cells, andmacrophages. PI3K δ is integrally involved in mammalian immune systemfunctions such as T-cell function, B-cell activation, mast cellactivation, dendritic cell function, and neutrophil activity. Due to itsintegral role in immune system function, PI3K δ is also involved in anumber of diseases related to undesirable immune response such asallergic reactions, inflammatory diseases, inflammation mediatedangiogenesis, rheumatoid arthritis, auto-immune diseases such as lupus,asthma, emphysema and other respiratory diseases. Other class I PI3Kinvolved in immune system function includes PI3K γ, which plays a rolein leukocyte signaling and has been implicated in inflammation,rheumatoid arthritis, and autoimmune diseases such as lupus.

Downstream mediators of the PI3K signal transduction pathway include Aktand mammalian target of rapamycin (mTOR). Akt possesses a plckstrinhomology (PH) domain that binds PIP3, leading to Akt kinase activation.Akt phosphorylates many substrates and is a central downstream effectorof PI3K for diverse cellular responses. One important function of Akt isto augment the activity of mTOR, through phosphorylation of TSC2 andother mechanisms. mTOR is a serine-threonine kinase related to the lipidkinases of the PI3K family. mTOR has been implicated in a wide range ofbiological processes including cell growth, cell proliferation, cellmotility and survival. Disregulation of the mTOR pathway has beenreported in various types of cancer. mTOR is a multifunctional kinasethat integrates growth factor and nutrient signals to regulate proteintranslation, nutrient uptake, autophagy, and mitochondrial function.

As such, kinases, particularly PI3Ks are prime targets for drugdevelopment. There remains a need for PI3K inhibitors suitable for drugdevelopment. The present invention addresses this need and providesrelated advantages as well by providing new classes of kinaseinhibitors.

“Isomers” are different compounds that have the same molecular formula.“Stereoisomers” are isomers that differ only in the way the atoms arearranged in space, i.e. having a different stereochemical configuration.“Enantiomers” are a pair of stereoisomers that are non-superimposablemirror images of each other. A 1:1 mixture of a pair of enantiomers is a“racemic” mixture. The term “(.±.)” is used to designate a racemicmixture where appropriate. “Diastereoisomers” are stereoisomers thathave at least two asymmetric atoms, but which are not mirror-images ofeach other. The absolute stereochemistry is specified according to theCahn-Ingold-Prelog R-S system. When a compound is a pure enantiomer thestereochemistry at each chiral carbon can be specified by either R or S.Resolved compounds whose absolute configuration is unknown can bedesignated (+) or (−) depending on the direction (dextro- orlevorotatory) which they rotate plane polarized light at the wavelengthof the sodium D line. Certain of the compounds described herein containone or more asymmetric centers and can thus give rise to enantiomers,diastereomers, and other stereoisomeric forms that can be defined, interms of absolute stereochemistry, as (R)- or (S)-. The present chemicalentities, pharmaceutical compositions and methods are meant to includeall such possible isomers, including racemic mixtures, optically pureforms and intermediate mixtures. Optically active (R)- and (S)-isomerscan be prepared using chiral synthons or chiral reagents, or resolvedusing conventional techniques. When the compounds described hereincontain olefinic double bonds or other centers of geometric asymmetry,and unless specified otherwise, it is intended that the compoundsinclude both E and Z geometric isomers.

“Enantiomeric purity” as used herein refers to the relative amounts,expressed as a percentage, of the presence of a specific enantiomerrelative to the other enantiomer. For example, if a compound, which maypotentially have an (R)- or an (S)-isomeric configuration, is present asa racemic mixture, the enantiomeric purity is about 50% with respect toeither the (R)- or (S)-isomer. If that compound has one isomeric formpredominant over the other, for example, 80% (S)- and 20% (R)-, theenantiomeric purity of the compound with respect to the (S)-isomericform is 80%. The enantiomeric purity of a compound can be determined ina number of ways known in the art, including but not limited tochromatography using a chiral support, polarimetric measurement of therotation of polarized light, nuclear magnetic resonance spectroscopyusing chiral shift reagents which include but are not limited tolanthanide containing chiral complexes or the Pirkle alcohol, orderivatization of a compounds using a chiral compound such as Mosher'sacid followed by chromatography or nuclear magnetic resonancespectroscopy.

“Moiety” refers to a specific segment or functional group of a molecule.Chemical moieties are often recognized chemical entities embedded in orappended to a molecule.

“Nitro” refers to the —NO₂ radical.

“Oxa” refers to the —O— radical.

“Oxo” refers to the ═O radical.

“Tautomers” are structurally distinct isomers that interconvert bytautomerization. “Tautomerization” is a form of isomerization andincludes prototropic or proton-shift tautomerization, which isconsidered a subset of acid-base chemistry. “Prototropictautomerization” or “proton-shift tautomerization” involves themigration of a proton accompanied by changes in bond order, often theinterchange of a single bond with an adjacent double bond. Wheretautomerization is possible (e.g. in solution), a chemical equilibriumof tautomers can be reached. An example of tautomerization is keto-enoltautomerization. A specific example of keto-enol tautomerization is theinterconversion of pentane-2,4-dione and 4-hydroxypent-3-en-2-onetautomers. Another example of tautomerization is phenol-ketotautomerization. A specific example of phenol-keto tautomerization isthe interconversion of pyridin-4-ol and pyridin-4(1H)-one tautomers.

The terms “enantiomerically enriched,” “enantiomerically pure” and“non-racemic,” as used interchangeably herein, refer to compositions inwhich the percent by weight of one enantiomer is greater than the amountof that one enantiomer in a control mixture of the racemic composition(e.g., greater than 1:1 by weight). For example, an enantiomericallyenriched preparation of the (S)-enantiomer, means a preparation of thecompound having greater than 50% by weight of the (S)-enantiomerrelative to the (R)-enantiomer, more preferably at least 75% by weight,and even more preferably at least 80% by weight. In some embodiments,the enrichment can be much greater than 80% by weight, providing a“substantially enantiomerically enriched,” “substantiallyenantiomerically pure” or a “substantially non-racemic” preparation,which refers to preparations of compositions which have at least 85% byweight of one enantiomer relative to other enantiomer, more preferablyat least 90% by weight, and even more preferably at least 95% by weight.

In preferred embodiments, the enantiomerically enriched composition hasa higher potency with respect to therapeutic utility per unit mass thandoes the racemic mixture of that composition. Enantiomers can beisolated from mixtures by methods known to those skilled in the art,including chiral high pressure liquid chromatography (HPLC) and theformation and crystallization of chiral salts; or preferred enantiomerscan be prepared by asymmetric syntheses. See, for example, Jacques, etal., Enantiomers, Racemates and Resolutions (Wiley Interscience, NewYork, 1981); Wilen, S. H., et al., Tetrahedron 33:2725 (1977); Eliel, E.L. Stereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); andWilen, S. H. Tables of Resolving Agents and Optical Resolutions p. 268(E. L. Eliel, Ed., Univ. of Notre Dame Press, Notre Dame, Ind. 1972).

All isotopic variations of the compounds ofthe present invention, whether radioactive or not, are encompassedwithin the scope of the present invention.

Described below are non-limiting exemplary pharmaceutical compositionsand methods for preparing the same.

Pharmaceutical Compositions for Oral Administration

In some embodiments, the invention provides a pharmaceutical compositionfor oral administration containing a compound of the present invention,and a pharmaceutical excipient suitable for oral administration.

In some embodiments, the invention provides a solid pharmaceuticalcomposition for oral administration containing: (i) an effective amountof a compound of the present invention; optionally (ii) an effectiveamount of a second agent; and (iii) a pharmaceutical excipient suitablefor oral administration. In some embodiments, the composition furthercontains: (iv) an effective amount of a third agent.

In some embodiments, the pharmaceutical composition may be a liquidpharmaceutical composition suitable for oral consumption. Pharmaceuticalcompositions of the invention suitable for oral administration can bepresented as discrete dosage forms, such as capsules, cachets, ortablets, or liquids or aerosol sprays each containing a predeterminedamount of an active ingredient as a powder or in granules, a solution,or a suspension in an aqueous or non-aqueous liquid, an oil-in-wateremulsion, or a water-in-oil liquid emulsion. Such dosage forms can beprepared by any of the methods of pharmacy, but all methods include thestep of bringing the active ingredient into association with thecarrier, which constitutes one or more necessary ingredients. Ingeneral, the compositions are prepared by uniformly and intimatelyadmixing the active ingredient with liquid carriers or finely dividedsolid carriers or both, and then, if necessary, shaping the product intothe desired presentation. For example, a tablet can be prepared bycompression or molding, optionally with one or more accessoryingredients. Compressed tablets can be prepared by compressing in asuitable machine the active ingredient in a free-flowing form such aspowder or granules, optionally mixed with an excipient such as, but notlimited to, a binder, a lubricant, an inert diluent, and/or a surfaceactive or dispersing agent. Molded tablets can be made by molding in asuitable machine a mixture of the powdered compound moistened with aninert liquid diluent.

This invention further encompasses anhydrous pharmaceutical compositionsand dosage forms comprising an active ingredient, since water canfacilitate the degradation of some compounds. For example, water may beadded (e.g., 5%) in the pharmaceutical arts as a means of simulatinglong-term storage in order to determine characteristics such asshelf-life or the stability of formulations over time. Anhydrouspharmaceutical compositions and dosage forms of the invention can beprepared using anhydrous or low moisture containing ingredients and lowmoisture or low humidity conditions. Pharmaceutical compositions anddosage forms of the invention which contain lactose can be madeanhydrous if substantial contact with moisture and/or humidity duringmanufacturing, packaging, and/or storage is expected. An anhydrouspharmaceutical composition may be prepared and stored such that itsanhydrous nature is maintained. Accordingly, anhydrous compositions maybe packaged using materials known to prevent exposure to water such thatthey can be included in suitable formulary kits. Examples of suitablepackaging include, but are not limited to, hermetically sealed foils,plastic or the like, unit dose containers, blister packs, and strippacks.

An active ingredient can be combined in an intimate admixture with apharmaceutical carrier according to conventional pharmaceuticalcompounding techniques. The carrier can take a wide variety of formsdepending on the form of preparation desired for administration. Inpreparing the compositions for an oral dosage form, any of the usualpharmaceutical media can be employed as carriers, such as, for example,water, glycols, oils, alcohols, flavoring agents, preservatives,coloring agents, and the like in the case of oral liquid preparations(such as suspensions, solutions, and elixirs) or aerosols; or carrierssuch as starches, sugars, micro-crystalline cellulose, diluents,granulating agents, lubricants, binders, and disintegrating agents canbe used in the case of oral solid preparations, in some embodimentswithout employing the use of lactose. For example, suitable carriersinclude powders, capsules, and tablets, with the solid oralpreparations. If desired, tablets can be coated by standard aqueous ornonaqueous techniques.

Binders suitable for use in pharmaceutical compositions and dosage formsinclude, but are not limited to, corn starch, potato starch, or otherstarches, gelatin, natural and synthetic gums such as acacia, sodiumalginate, alginic acid, other alginates, powdered tragacanth, guar gum,cellulose and its derivatives (e.g., ethyl cellulose, cellulose acetate,carboxymethyl cellulose calcium, sodium carboxymethyl cellulose),polyvinyl pyrrolidone, methyl cellulose, pre-gelatinized starch,hydroxypropyl methyl cellulose, microcrystalline cellulose, and mixturesthereof.

Examples of suitable fillers for use in the pharmaceutical compositionsand dosage forms disclosed herein include, but are not limited to, talc,calcium carbonate (e.g., granules or powder), microcrystallinecellulose, powdered cellulose, dextrates, kaolin, mannitol, silicicacid, sorbitol, starch, pre-gelatinized starch, and mixtures thereof.

Disintegrants may be used in the compositions of the invention toprovide tablets that disintegrate when exposed to an aqueousenvironment. Too much of a disintegrant may produce tablets which maydisintegrate in the bottle. Too little may be insufficient fordisintegration to occur and may thus alter the rate and extent ofrelease of the active ingredient(s) from the dosage form. Thus, asufficient amount of disintegrant that is neither too little nor toomuch to detrimentally alter the release of the active ingredient(s) maybe used to form the dosage forms of the compounds disclosed herein. Theamount of disintegrant used may vary based upon the type of formulationand mode of administration, and may be readily discernible to those ofordinary skill in the art. About 0.5 to about 15 weight percent ofdisintegrant, or about 1 to about 5 weight percent of disintegrant, maybe used in the pharmaceutical composition. Disintegrants that can beused to form pharmaceutical compositions and dosage forms of theinvention include, but are not limited to, agar-agar, alginic acid,calcium carbonate, microcrystalline cellulose, croscarmellose sodium,crospovidone, polacrilin potassium, sodium starch glycolate, potato ortapioca starch, other starches, pre-gelatinized starch, other starches,clays, other algins, other celluloses, gums or mixtures thereof.

Lubricants which can be used to form pharmaceutical compositions anddosage forms of the invention include, but are not limited to, calciumstearate, magnesium stearate, mineral oil, light mineral oil, glycerin,sorbitol, mannitol, polyethylene glycol, other glycols, stearic acid,sodium lauryl sulfate, talc, hydrogenated vegetable oil (e.g., peanutoil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil, andsoybean oil), zinc stearate, ethyl oleate, ethylaureate, agar, ormixtures thereof. Additional lubricants include, for example, a syloidsilica gel, a coagulated aerosol of synthetic silica, or mixturesthereof. A lubricant can optionally be added, in an amount of less thanabout 1 weight percent of the pharmaceutical composition.

When aqueous suspensions and/or elixirs are desired for oraladministration, the essential active ingredient therein may be combinedwith various sweetening or flavoring agents, coloring matter or dyesand, if so desired, emulsifying and/or suspending agents, together withsuch diluents as water, ethanol, propylene glycol, glycerin and variouscombinations thereof.

The tablets can be uncoated or coated by known techniques to delaydisintegration and absorption in the gastrointestinal tract and therebyprovide a sustained action over a longer period. For example, a timedelay material such as glyceryl monostearate or glyceryl distearate canbe employed. Formulations for oral use can also be presented as hardgelatin capsules wherein the active ingredient is mixed with an inertsolid diluent, for example, calcium carbonate, calcium phosphate orkaolin, or as soft gelatin capsules wherein the active ingredient ismixed with water or an oil medium, for example, peanut oil, liquidparaffin or olive oil.

Surfactant which can be used to form pharmaceutical compositions anddosage forms of the invention include, but are not limited to,hydrophilic surfactants, lipophilic surfactants, and mixtures thereof.That is, a mixture of hydrophilic surfactants may be employed, a mixtureof lipophilic surfactants may be employed, or a mixture of at least onehydrophilic surfactant and at least one lipophilic surfactant may beemployed.

A suitable hydrophilic surfactant may generally have an HLB value of atleast 10, while suitable lipophilic surfactants may generally have anHLB value of or less than about 10. An empirical parameter used tocharacterize the relative hydrophilicity and hydrophobicity of non-ionicamphiphilic compounds is the hydrophilic-lipophilic balance (“HLB”value). Surfactants with lower HLB values are more lipophilic orhydrophobic, and have greater solubility in oils, while surfactants withhigher HLB values are more hydrophilic, and have greater solubility inaqueous solutions. Hydrophilic surfactants are generally considered tobe those compounds having an HLB value greater than about 10, as well asanionic, cationic, or zwitterionic compounds for which the HLB scale isnot generally applicable. Similarly, lipophilic (i.e., hydrophobic)surfactants are compounds having an HLB value equal to or less thanabout 10. However, HLB value of a surfactant is merely a rough guidegenerally used to enable formulation of industrial, pharmaceutical andcosmetic emulsions.

Administration of the compounds or pharmaceutical composition of thepresent invention can be effected by any method that enables delivery ofthe compounds to the site of action. These methods include oral routes,intraduodenal routes, parenteral injection (including intravenous,intraarterial, subcutaneous, intramuscular, intravascular,intraperitoneal or infusion), topical (e.g. transdermal application),rectal administration, via local delivery by catheter or stent orthrough inhalation. Compounds can also abe administered intraadiposallyor intrathecally.

The amount of the compound administered will be dependent on the mammalbeing treated, the severity of the disorder or condition, the rate ofadministration, the disposition of the compound and the discretion ofthe prescribing physician. However, an effective dosage is in the rangeof about 0.001 to about 100 mg per kg body weight per day, preferablyabout 1 to about 35 mg/kg/day, in single or divided doses. For a 70 kghuman, this would amount to about 0.05 to 7 g/day, preferably about 0.05to about 2.5 g/day. In some instances, dosage levels below the lowerlimit of the aforesaid range may be more than adequate, while in othercases still larger doses may be employed without causing any harmfulside effect, e.g. by dividing such larger doses into several small dosesfor administration throughout the day.

In some embodiments, a compound of the invention is administered in asingle dose. Typically, such administration will be by injection, e.g.,intravenous injection, in order to introduce the agent quickly. However,other routes may be used as appropriate. A single dose of a compound ofthe invention may also be used for treatment of an acute condition.

In some embodiments, a compound of the invention is administered inmultiple doses. Dosing may be about once, twice, three times, fourtimes, five times, six times, or more than six times per day. Dosing maybe about once a month, once every two weeks, once a week, or once everyother day. In another embodiment a compound of the invention and anotheragent are administered together about once per day to about 6 times perday. In another embodiment the administration of a compound of theinvention and an agent continues for less than about 7 days. In yetanother embodiment the administration continues for more than about 6,10, 14, 28 days, two months, six months, or one year. In some cases,continuous dosing is achieved and maintained as long as necessary.

Administration of the agents of the invention may continue as long asnecessary. In some embodiments, an agent of the invention isadministered for more than 1, 2, 3, 4, 5, 6, 7, 14, or 28 days. In someembodiments, an agent of the invention is administered for less than 28,14, 7, 6, 5, 4, 3, 2, or 1 day. In some embodiments, an agent of theinvention is administered chronically on an ongoing basis, e.g., for thetreatment of chronic effects.

An effective amount of a compound of the invention may be administeredin either single or multiple doses by any of the accepted modes ofadministration of agents having similar utilities, including rectal,buccal, intranasal and transdermal routes, by intra-arterial injection,intravenously, intraperitoneally, parenterally, intramuscularly,subcutaneously, orally, topically, or as an inhalant.

The compositions of the invention may also be delivered via animpregnated or coated device such as a stent, for example, or anartery-inserted cylindrical polymer. Such a method of administrationmay, for example, aid in the prevention or amelioration of restenosisfollowing procedures such as balloon angioplasty. Without being bound bytheory, compounds of the invention may slow or inhibit the migration andproliferation of smooth muscle cells in the arterial wall whichcontribute to restenosis. A compound of the invention may beadministered, for example, by local delivery from the struts of a stent,from a stent graft, from grafts, or from the cover or sheath of a stent.In some embodiments, a compound of the invention is admixed with amatrix. Such a matrix may be a polymeric matrix, and may serve to bondthe compound to the stent. Polymeric matrices suitable for such use,include, for example, lactone-based polyesters or copolyesters such aspolylactide, polycaprolactonglycolide, polyorthoesters, polyanhydrides,polyaminoacids, polysaccharides, polyphosphazenes, poly (ether-ester)copolymers (e.g. PEO-PLLA); polydimethylsiloxane,poly(ethylene-vinylacetate), acrylate-based polymers or copolymers (e.g.polyhydroxyethyl methylmethacrylate, polyvinyl pyrrolidinone),fluorinated polymers such as polytetrafluoroethylene and celluloseesters. Suitable matrices may be nondegrading or may degrade with time,releasing the compound or compounds. Compounds of the invention may beapplied to the surface of the stent by various methods such as dip/spincoating, spray coating, dip-coating, and/or brush-coating. The compoundsmay be applied in a solvent and the solvent may be allowed to evaporate,thus forming a layer of compound onto the stent. Alternatively, thecompound may be located in the body of the stent or graft, for examplein microchannels or micropores. When implanted, the compound diffusesout of the body of the stent to contact the arterial wall. Such stentsmay be prepared by dipping a stent manufactured to contain suchmicropores or microchannels into a solution of the compound of theinvention in a suitable solvent, followed by evaporation of the solvent.Excess drug on the surface of the stent may be removed via an additionalbrief solvent wash. In yet other embodiments, compounds of the inventionmay be covalently linked to a stent or graft. A covalent linker may beused which degrades in vivo, leading to the release of the compound ofthe invention. Any bio-labile linkage may be used for such a purpose,such as ester, amide or anhydride linkages. Compounds of the inventionmay additionally be administered intravascularly from a balloon usedduring angioplasty. Extravascular administration of the compounds viathe pericard or via advential application of formulations of theinvention may also be performed to decrease restenosis.

Example 22 Expression and Inhibition Assays of p110α/p85α, p110β/p85α,p110δ/p85α, and p110γ

Class I PI3-Ks can be either purchased (p110α/p85α, p110β/p85α,p110δ/p85α from Upstate, and p110γ from Sigma) or expressed aspreviously described (Knight et al., 2004). IC50 values are measuredusing either a standard TLC assay for lipid kinase activity (describedbelow) or a high-throughput membrane capture assay. Kinase reactions areperformed by preparing a reaction mixture containing kinase, inhibitor(2% DMSO final concentration), buffer (25 mM HEPES, pH 7.4, 10 mMMgCl2), and freshly sonicated phosphatidylinositol (100 μg/ml).Reactions are initiated by the addition of ATP containing 10 μCi ofγ-32P-ATP to a final concentration 10 or 100 μM and allowed to proceedfor 5 minutes at room temperature. For TLC analysis, reactions are thenterminated by the addition of 105 μl 1N HCl followed by 160 μlCHCl3:MeOH (1:1). The biphasic mixture is vortexed, briefly centrifuged,and the organic phase is transferred to a new tube using a gel loadingpipette tip precoated with CHCl₃. This extract is spotted on TLC platesand developed for 3-4 hours in a 65:35 solution of n-propanol:1M aceticacid. The TLC plates are then dried, exposed to a phosphorimager screen(Storm, Amersham), and quantitated. For each compound, kinase activityis measured at 10-12 inhibitor concentrations representing two-folddilutions from the highest concentration tested (typically, 200 μM). Forcompounds showing significant activity, IC50 determinations are repeatedtwo to four times, and the reported value is the average of theseindependent measurements.

Other commercial kits or systems for assaying PI3-K activities areavailable. The commercially available kits or systems can be used toscreen for inhibitors and/or agonists of PI3-Ks including but notlimited to PI 3-Kinase α, β, δ, and γ. Anm exemplary system is PI3-Kinase (human) HTRF™ Assay from Upstate. The assay can be carried outaccording to the procedures suggested by the manufacturer. Briefly, theassay is a time resolved FRET assay that indirectly measures PIP3product formed by the activity of a PI3-K. The kinase reaction isperformed in a microtitre plate (e.g., a 384 well microtitre plate). Thetotal reaction volume is approximately 20 ul per well. In the firststep, each well receives 2 ul of test compound in 20% dimethylsulphoxideresulting in a 2% DMSO final concentration. Next, approximately 14.5 ulof a kinase/PIP2 mixture (diluted in 1× reaction buffer) is added perwell for a final concentration of 0.25-0.3 ug/ml kinase and 10 uM PIP2.The plate is sealed and incubated for 15 minutes at room temperature. Tostart the reaction, 3.5 ul of ATP (diluted in 1× reaction buffer) isadded per well for a final concentration of 10 uM ATP. The plate issealed and incubated for 1 hour at room temperature. The reaction isstopped by adding 5 ul of Stop Solution per well and then 5 ul ofDetection Mix is added per well. The plate is sealed, incubated for 1hour at room temperature, and then read on an appropriate plate reader.Data is analyzed and IC50s are generated using GraphPad Prism 5.

Example 40 Microsome Stability Assay

The stability of one or more subject compounds is determined accordingto standard procedures known in the art.

For example, stability of one or more subject compounds is establishedby an in vitro assay. In particular, an in vitro microsome stabilityassay is established that measures stability of one or more subjectcompounds when reacting with mouse, rat or human microsomes from liver.The microsome reaction with compounds is performed in 1.5 mL Eppendorftube. Each tube contains 0.1 μL of 10.0 mg/ml NADPH; 75 μL of 20.0 mg/mlmouse, rat or human liver microsome; 0.4 μL of 0.2 M phosphate buffer,and 425 μL of ddH₂O. Negative control (without NADPH) tube contains 75μL of 20.0 mg/ml mouse, rat or human liver microsome; 0.4 μL of 0.2 Mphosphate buffer, and 525 μL of ddH₂O. The reaction is started by adding1.0 μL of 10.0 mM tested compound. The reaction tubes are incubated at37° C. 100 μL sample is collected into new Eppendorf tube containing 300μL cold Methanol at 0, 5, 10, 15, 30 and 60 minutes of reaction. Samplesare centrifuged at 15,000 rpm to remove protein. Supernatant ofcentrifuged sample is transferred to new tube. Concentration of stablecompound after reaction with microsome in the supernatant is measured byLiquid Chromatography/Mass Spectrometry (LC-MS).

Example 41 Plasma Stability Assay

The stability of one or more subject compounds in plasma is determinedaccording to standard procedures known in the art. See, e.g., RapidCommun. Mass Spectrom., 10: 1019-1026. The following procedure is anHPLC-MS/MS assay using human plasma; other species including monkey,dog, rat, and mouse are also available. Frozen, heparinized human plasmais thawed in a cold water bath and spun for 10 minutes at 2000 rpm at 4°C. prior to use. A subject compound is added from a 400 μM stocksolution to an aliquot of pre-warmed plasma to give a final assay volumeof 400 μL (or 800 μL for half-life determination), containing 5 μM testcompound and 0.5% DMSO. Reactions are incubated, with shaking, for 0minutes and 60 minutes at 37° C., or for 0, 15, 30, 45 and 60 minutes at37° C. for half life determination. Reactions are stopped bytransferring 50 μL of the incubation mixture to 200 μL of ice-coldacetonitrile and mixed by shaking for 5 minutes. The samples arecentrifuged at 6000×g for 15 minutes at 4° C. and 120 μL of supernatantremoved into clean tubes. The samples are then evaporated to dryness andsubmitted for analysis by HPLC-MS/MS.

Where desired, one or more control or reference compounds (5 μM) aretested simultaneously with the test compounds: one compound,propoxycaine, with low plasma stability and another compound,propantheline, with intermediate plasma stability.

Samples are reconstituted in acetonitrile/methanol/water (1/1/2, v/v/v)and analyzed via (RP)HPLC-MS/MS using selected reaction monitoring(SRM). The HPLC conditions consist of a binary LC pump with autosampler,a mixed-mode, C12, 2×20 mm column, and a gradient program. Peak areascorresponding to the analytes are recorded by HPLC-MS/MS. The ratio ofthe parent compound remaining after 60 minutes relative to the amountremaining at time zero, expressed as percent, is reported as plasmastability. In case of half-life determination, the half-life isestimated from the slope of the initial linear range of the logarithmiccurve of compound remaining (%) vs. time, assuming first order kinetics.

Example 42 Chemical Stability

The chemical stability of one or more subject compounds is determinedaccording to standard procedures known in the art. The following detailsan exemplary procedure for ascertaining chemical stability of a subjectcompound. The default buffer used for the chemical stability assay isphosphate-buffered saline (PBS) at pH 7.4; other suitable buffers can beused. A subject compound is added from a 100 μM stock solution to analiquot of PBS (in duplicate) to give a final assay volume of 400 μL,containing 5 μM test compound and 1% DMSO (for half-life determination atotal sample volume of 700 μL is prepared). Reactions are incubated,with shaking, for 0 minutes and 24 hours at 37° C.; for half-lifedetermination samples are incubated for 0, 2, 4, 6, and 24 hours.Reactions are stopped by adding immediately 100 μL of the incubationmixture to 100 μL of acetonitrile and vortexing for 5 minutes. Thesamples are then stored at −20° C. until analysis by HPLC-MS/MS. Wheredesired, a control compound or a reference compound such as chlorambucil(5 μM) is tested simultaneously with a subject compound of interest, asthis compound is largely hydrolyzed over the course of 24 hours. Samplesare analyzed via (RP)HPLC-MS/MS using selected reaction monitoring(SRM). The HPLC conditions consist of a binary LC pump with autosampler,a mixed-mode, C12, 2×20 mm column, and a gradient program. Peak areascorresponding to the analytes are recorded by HPLC-MS/MS. The ratio ofthe parent compound remaining after 24 hours relative to the amountremaining at time zero, expressed as percent, is reported as chemicalstability. In case of half-life determination, the half-life isestimated from the slope of the initial linear range of the logarithmiccurve of compound remaining (%) vs. time, assuming first order kinetics.

Example 43 Akt Kinase Assay

Cells comprising components of the Akt/mTOR pathway, including but notlimited to L6 myoblasts, B-ALL cells, B-cells, T-cells, leukemia cells,bone marrow cells, p190 transduced cells, philladelphia chromosomepositive cells (Ph+), and mouse embryonic fibroblasts, are typicallygrown in cell growth media such as DMEM supplemented with fetal bovineserum and/or antibiotics, and grown to confluency.

In order to compare the effect of one or more compounds disclosed hereinon Akt activation, said cells are serum starved overnight and incubatedwith one or more compounds disclosed herein or about 0.1% DMSO forapproximately 1 minute to about 1 hour prior to stimulation with insulin(e.g. 100 nM) for about 1 minutes to about 1 hour. Cells are lysed byscraping into ice cold lysis buffer containing detergents such as sodiumdodecyl sulfate and protease inhibitors (e.g., PMSF). After contactingcells with lysis buffer, the solution is briefly sonicated, cleared bycentrifugation, resolved by SDS-PAGE, transferred to nitrocellulose orPVDF and immunoblotted using antibodies to phospho-Akt S473, phospho-AktT308, Akt, and β-actin (Cell Signaling Technologies).

The results demonstrate that one or more compounds of the presentdisclosure inhibit insulin stimulated phosphorylation of Akt at S473.Alternatively, some compounds disclosed herein additionally inhibitinsulin stimulated phosphorylation of Akt at T308. Such class ofcompounds can inhibit Akt more effectively than rapamycin and may beindicative of mTORC2 inhibitors or inhibitors of upstream kinases suchas PI3K or Akt.

Example 44 Kinase Signaling in Blood

PI3K/Akt/mTor signaling is measured in blood cells using the phosflowmethod (Methods Enzymol. 2007; 434:131-54). The advantage of this methodis that it is by nature a single cell assay so that cellularheterogeneity can be detected rather than population averages. Thisallows concurrent distinction of signaling states in differentpopulations defined by other markers. Phosflow is also highlyquantitative. To test the effects of one or more compounds disclosedherein, unfractionated splenocytes, or peripheral blood mononuclearcells are stimulated with anti-CD3 to initiate T-cell receptorsignaling. The cells are then fixed and stained for surface markers andintracellular phosphoproteins. It is expected that inhibitors disclosedherein inhibit anti-CD3 mediated phosphorylation of Akt-S473 and S6,whereas rapamycin inhibits S6 phosphorylation and enhances Aktphosphorylation under the conditions tested.

Similarly, aliquots of whole blood are incubated for 15 minutes withvehicle (e.g. 0.1% DMSO) or kinase inhibitors at various concentrations,before addition of stimuli to crosslink the T cell receptor (TCR)(anti-CD3 with secondary antibody) or the B cell receptor (BCR) usinganti-kappa light chain antibody (Fab′2 fragments). After approximately 5and 15 minutes, samples are fixed (e.g. with cold 4% paraformaldehyde)and used for phosflow. Surface staining is used to distinguish T and Bcells using antibodies directed to cell surface markers that are knownto the art. The level of phosphrylation of kinase substrates such as Aktand S6 are then measured by incubating the fixed cells with labeledantibodies specific to the phosphorylated isoforms of these proteins.The population of cells are then analyzed by flow cytometry.

Example 45 Colony Formation Assay

Murine bone marrow cells freshly transformed with a p190 BCR-Ablretrovirus (herein referred to as p190 transduced cells) are plated inthe presence of various drug combinations in M3630 methylcellulose mediafor about 7 days with recombinant human IL-7 in about 30% serum, and thenumber of colonies formed is counted by visual examination under amicroscope.

Alternatively, human peripheral blood mononuclear cells are obtainedfrom Philadelphia chromosome positive (Ph+) and negative (Ph−) patientsupon initial diagnosis or relapse. Live cells are isolated and enrichedfor CD19+CD34+ B cell progenitors. After overnight liquid culture, cellsare plated in methocult GF+H4435, Stem Cell Tehcnologies) supplementedwith cytokines (IL-3, IL-6, IL-7, G-CSF, GM-CSF, CF, Flt3 ligand, anderythropoietin) and various concentrations of known chemotherapeuticagents in combination with either compounds of the present disclosure.Colonies are counted by microscopy 12-14 days later. This method can beused to test for evidence of additive or synergistic activity.

Example 46 In Vivo Effect of Kinase Inhibitors on Leukemic Cells

Female recipient mice are lethally irradiated from a γ source in twodoses about 4 hr apart, with approximately 5Gy each. About 1 hr afterthe second radiation dose, mice are injected i.v. with about 1×10⁶leukemic cells (e.g. Ph+ human or murine cells, or p190 transduced bonemarrow cells). These cells are administered together with aradioprotective dose of about 5×10⁶ normal bone marrow cells from 3-5week old donor mice. Recipients are given antibiotics in the water andmonitored daily. Mice who become sick after about 14 days are euthanizedand lymphoid organs are harvested for analysis. Kinase inhibitortreatment begins about 10 days after leukemic cell injection andcontinues daily until the mice become sick or a maximum of approximately35 days post-transplant. Inhibitors are given by oral lavage.

Peripheral blood cells are collected approximately on day 10(pre-treatment) and upon euthanization (post treatment), contacted withlabeled anti-hCD4 antibodies and counted by flow cytometry. This methodcan be used to demonstrate that the synergistic effect of one or morecompounds disclosed herein in combination with known chemotherapeuticagents significantly reduce leukemic blood cell counts as compared totreatment with known chemotherapeutic agents (e.g. Gleevec) alone underthe conditions tested.

Example 47 Treatment of Lupus Disease Model Mice

Mice lacking the inhibitory receptor FcγRIIb that opposes PI3K signalingin B cells develop lupus with high penetrance. FcγRIIb knockout mice(R2KO, Jackson Labs) are considered a valid model of the human diseaseas some lupus patients show decreased expression or function of FcγRIIb(S. Bolland and J. V. Ravtech 2000. Immunity 12:277-285).

The R2KO mice develop lupus-like disease with anti-nuclear antibodies,glomerulonephritis and proteinurea within about 4-6 months of age. Forthese experiments, the rapamycin analogue RAD001 (available from LCLaboratories) is used as a benchmark compound, and administered orally.This compound has been shown to ameliorate lupus symptoms in theB6.Slelz.Sle3z model (T. Wu et al. J. Clin Invest. 117:2186-2196).

Lupus disease model mice such as R2KO, BXSB or MLR/lpr are treated atabout 2 months old, approximately for about two months. Mice are givendoses of: vehicle, RAD001 at about 10 mg/kg, or compounds disclosedherein at approximately 1 mg/kg to about 500 mg/kg. Blood and urinesamples are obtained at approximately throughout the testing period, andtested for antinuclear antibodies (in dilutions of serum) or proteinconcentration (in urine). Serum is also tested for anti-ssDNA andanti-dsDNA antibodies by ELISA. Animals are euthanized at day 60 andtissues harvested for measuring spleen weight and kidney disease.Glomerulonephritis is assessed in kidney sections stained with H&E.Other animals are studied for about two months after cessation oftreatment, using the same endpoints.

This model established in the art can be employed to demonstrate thatthe kinase inhibitors disclosed herein can suppress or delay the onsetof lupus symptoms in lupus disease model mice.

Example 48 Murine Bone Marrow Transplant Assay

Female recipient mice are lethally irradiated from a γ ray source. About1 hr after the radiation dose, mice are injected with about 1×106leukemic cells from early passage p190 transduced cultures (e.g. asdescribed in Cancer Genet Cytogenet. 2005 August; 161(1):51-6). Thesecells are administered together with a radioprotective dose ofapproximately 5×106 normal bone marrow cells from 3-5 wk old donor mice.Recipients are given antibiotics in the water and monitored daily. Micewho become sick after about 14 days are euthanized and lymphoid organsharvested for flow cytometry and/or magnetic enrichment. Treatmentbegins on approximately day 10 and continues daily until mice becomesick, or after a maximum of about 35 days post-transplant. Drugs aregiven by oral gavage (p.o.). In a pilot experiment a dose ofchemotherapeutic that is not curative but delays leukemia onset by aboutone week or less is identified; controls are vehicle-treated or treatedwith chemotherapeutic agent, previously shown to delay but not cureleukemogenesis in this model (e.g. imatinib at about 70 mg/kg twicedaily). For the first phase p190 cells that express eGFP are used, andpostmortem analysis is limited to enumeration of the percentage ofleukemic cells in bone marrow, spleen and lymph node (LN) by flowcytometry. In the second phase, p190 cells that express a tailless formof human CD4 are used and the postmortem analysis includes magneticsorting of hCD4+ cells from spleen followed by immunoblot analysis ofkey signaling endpoints: p Akt-T308 and S473; pS6 and p4EBP-1. Ascontrols for immunoblot detection, sorted cells are incubated in thepresence or absence of kinase inhibitors of the present disclosureinhibitors before lysis. Optionally, “phosflow” is used to detect pAkt-S473 and pS6-S235/236 in hCD4-gated cells without prior sorting.These signaling studies are particularly useful if, for example,drug-treated mice have not developed clinical leukemia at the 35 daytime point. Kaplan-Meier plots of survival are generated and statisticalanalysis done according to methods known in the art. Results from p190cells are analyzed separated as well as cumulatively.

Samples of peripheral blood (100-200 μl) are obtained weekly from allmice, starting on day 10 immediately prior to commencing treatment.Plasma is used for measuring drug concentrations, and cells are analyzedfor leukemia markers (eGFP or hCD4) and signaling biomarkers asdescribed herein.

This general assay known in the art may be used to demonstrate thateffective therapeutic doses of the compounds disclosed herein can beused for inhibiting the proliferation of leukemic cells.

Example 49 TNP-Ficoll T-Cell Independent B-Cell Activation Assay

Compounds of thepresent invention were dissolved in an appropriate vehicle (e.g. 5%1-methyl-2-pyrrolidinone, 85% polyethylene glycol 400, 10% Solutor).Compounds were administered orally approximately 1 hr before TNP-Ficolltreatment to 4-10 week old mice. To study the effects of the compoundson B-cell activation, one set of mice were grouped according to thefollowing table:

Antigen Compound injection at Administration from Mice/ Comp day-1 day-1to day-7 Group# group treated Group TNP-F Route (mg/kg) Route Regimen 14 Vehicle Antigen only 200 uL ip 0 Po BID for 7 2 8 — Antigen only (0.5mg/ml) 0 days 3 8 Compound reference 30 #7 4 8 Compound Antigen + cmp 15 8 #53 3 6 8 10 7 8 30 8 8 60

Four animals in group 1, and eight animals in groups 2 to 7 wereeuthanized in CO₂ 2 hours after the last compound administration on day7. Blood was immediately collected by cadio-puncture and kept at 37° C.for 1 hr to clot followed by overnight incubation at 4° C. to allow theclot to contract. The following day, serum was collected by decantingand centrifugation at 3000 rpm for 10 min. The collected serum was thenfrozen at −80° C. for future analysis.

Serum samples were analyzed for anti-TNP antibody titers by ELISA asdescribed herein. TNP-BSA was coated onto a Nunc Maxisorb microtiterplate with 100 μl/well at a concentration of 10 μg/ml in phosphatebuffered saline (PBS). The Maxisorb plate was incubated for 1.5 hours atroom temperature and the solution was removed. 200 μl/well of blockingbuffer (e.g. 1% BSA in PBS) was added to each well and incubated 1 hr atroom temperature. The plate was washed once with 200 μl/well of PBS0.05% Tween-20 (wash buffer). A 1:2 dilution of serum from each mouse inblocking buffer was added to each well in the first column (1) of themicrotiter plate. The serum in each well of column 1 was then diluted3-fold in blocking buffer and added to column 2. The serum in each wellof column 2 was diluted 3-fold in blocking buffer and added to column 3.The procedure was repeated across the twelve columns of the microtiterplate. The microtiter plate was incubated 1 hr at room temperature.Serum was removed from the plate and the plate was washed three timeswith wash buffer. 100 l/well of goat anti-mouse IgG3-HRP diluted 1:250in blocking buffer was added to each well and incubated 1 hr at roomtemperature. The anti-mouse IgG3-HRP was removed from the microtiterplate and the plate was washed six times with wash buffer. HRP substrate(200 μl ABTS solution+30% H₂O₂+10 ml citrate buffer) was added to eachwell at 100 μl/well, incubated 2-20 minutes in the dark and the amountof anti-TNP IgG3 was determined spectrophotometrically at 405 nm.Similarly, anti-TNP IgM and total anti-TNP Ab were determined usinganti-mouse IgM-HRP and anti-mouse Ig-HRP respectively.

The results as shown in FIG. 2 futher show that under the conditionstested compounds #7 and #53 exhibit 3.4 and 6.5-fold reductionsrespectively in IgG3 levels relative to vehicle control mice at a 30mg/kg dose level. FIG. 2 further shows that compound #53 exhibits29.9-fold reduction in IgG3 levels relative to vehicle control mice at a60 mg/kg dose level under the conditions tested.

Example 51 Rat Established Type II Collagen Induced Arthritis Assay

In order to examine the dose responsive efficacy of the compounds of thepresent invention in inhibiting the inflammation, cartilage destructionand bone resorption of 10 day established type II collagen inducedarthritis in rats, compounds were administered orally daily or twicedaily for 6 days.

Female Lewis rats were anesthetized and given collagen injectionsprepared and administered as described previously on day 0. On day 6,animals were anesthetized and given a second collagen injection. Calipermeasurements of normal (pre-disease) right and left ankle joints wereperformed on day 9. On days 10-11, arthritis typically occurred and ratswere randomized into treatment groups. Randomization was performed afterankle joint swelling was obviously established and there was goodevidence of bilateral disease.

After an animal was selected for enrollment in the study, treatment wasinitiated by the oral route. Animals were given vehicle, control(Enbrel) or compound doses, twice daily or once daily (BID or QDrespectively). Dosing was administered on days 1-6 using a volume of 2.5ml/kg (BID) or 5 ml/kg (QD) for oral solutions. Rats were weighed ondays 1-7 following establishment of arthritis and caliper measurements fankles taken every day. Final body weights were taken on day 7 andanimals were euthanized.

The results as shown in FIG. 8 shows a significant reduction in meanankle diameter increase over time for compound #53 with a once dailydosage under the conditions tested. The results in FIG. 9 futherdemonstrate a significant reduction in mean ankle diameter increase overtime for compound #53 with a twice daily dosage under the conditionstested.

Whentested in the same model, at least five other compounds of the presentinvention exhibit comparable or even higher efficacy as compared tocompound #53.

Example 52 Adjuvant Induced Arthritis Assay Intrathecal Catheterizationof Rats

Isoflurane-anesthetized Lewis rats (200-250 g) were implanted with anintrathecal (IT) catheter. After a 6 d recovery period, all animalsexcept those that appeared to have sensory or motor abnormalities (fewerthan 5% of the total number) were used for experiments. For ITadministration, 10 μl of drug or saline followed by 10 μl of isotonicsaline was injected through the catheter.

Adjuvant Arthritis and Drug Treatment

Lewis rats were immunized at the base of the tail with 0.1 ml ofcomplete Freund's adjuvant (CFA) on day 0 several days after catheterimplantation (n=6/group). Drug (e.g. one or more compounds of thepresent invention or vehicle) treatment was generally started on day 8and continued daily until day 20. Clinical signs of arthritis generallybegin on day 10, and paw swelling was determined every second day bywater displacement plethysmometry.

The results as depicted in FIG. 10 by the average change in paw volumeunder the dosage regimes indicated show that under the conditionstested, compound #53 shows a dose dependent reduction in the average pawvolume increase as measured in this adjuvant induced arthritis modelsystem. These results suggest that one or more of the compounds of thepresent invention may be useful for the treatment of one or more of thediseases or conditions described herein.

Example 53 Rodent Pharmacokinetic Assay

In order to study the pharmacokinetics of the compounds of the presentinvention a set of 4-10 week old mice are grouped according to thefollowing table:

Compound Administration Mice/ from day-1 to day-7 Group# group (mg/kg)Route Regimen 1 3 1 Po BID for 7 2 3 3 days 3 3 10 4 3 30 5 3 60

Compounds of the present invention are dissolved in an appropriatevehicle (e.g. 5% 1-methyl-2-pyrrolidinone, 85% polyethylene glycol 400,10% Solutor) and administered orally at 12 hour intervals daily. Allanimals are euthanized in CO₂ 2 hours after the final compound isadministered. Blood is collected immediately and kept on ice for plasmaisolation. Plasma is isolated by centrifuging at 5000 rpm for 10minutes. Harvested plasma is frozen for pharmacokinetic detection.

The results are expected to demonstrate the pharmacokinetic parameterssuch as absorption, distribution, metabolism, excretion, and toxicityfor the compounds of the present invention.

Example 54 Basotest Assay

The baseotest assay is performed using Orpegen Pharma Basotest reagentkit. Heparinized whole blood is pre-incubated with test compound orsolvent at 37 C for 20 min. Blood is then incubated with assay kitstimulation buffer (to prime cells for response) followed by allergen(dust mite extract or grass extract) for 20 min. The degranulationprocess is stopped by incubating the blood samples on ice. The cells arethen labeled with anti-IgE-PE to detect basophilic granulocytes, andanti-gp53-FITC to detect gp53 (a glycoprotein expressed on activatedbasophils). After staining red blood cells are lysed by addition ofLysing Solution. Cells are washed, and analyzed by flow cytometry.Compounds 7 and 53 when tested in this assay inhibit allergen inducedactivation of basophilic granulocytes at sub micromolar range.

Example 55 Combination Use of PI3K6 Inhibitors and Agents that InhibitIgE Production or Activity

The compounds of the present invention may present synergistic oradditive efficacy when administered in combination with agents thatinhibit IgE production or activity. Agents that inhibit IgE productioninclude, for example, one or more of TEI-9874,2-(4-(6-cyclohexyloxy-2-naphtyloxy)phenylacetamide)benzoic acid,rapamycin, rapamycin analogs (i.e. rapalogs), TORC1 inhibitors, TORC2inhibitors, and any other compounds that inhibit mTORC1 and mTORC2.Agents that inhibit IgE activity include, for example, anti-IgEantibodies such as Omalizumab and TNX-901.

One or more of the subject compounds capable of inhibiting PI3Kδ areefficacious in treatment of autoimmune and inflammatory disorders (AIID)for example rheumatoid arthritis. If any of the compounds causes anundesired level of IgE production, one may choose to administer it incombination with an agent that inhibits IgE production or IgE activity.Additionally, the administration of PI3Kδ or PI3Kδ/γ inhibitors of thepresent invention in combination with inhibitors of mTOR may alsoexhibit synergy through enhanced inhibition of the PI3K pathway. Variousin vivo and in vitro models may be used to establish the effect of suchcombination treatment on AIID including but not limited to (a) in vitroB-cell antibody production assay, (b) in vivo TNP assay, and (c) rodentcollagen induced arthritis model.

(a) B-Cell Assay

Mice are euthanized, and the spleens are removed and dispersed through anylon mesh to generate a single-cell suspension. The splenocytes arewashed (following removal of erythrocytes by osmotic shock) andincubated with anti-CD43 and anti-Mac-1 antibody-conjugated microbeads(Miltenyi Biotec). The bead-bound cells are separated from unbound cellsusing a magnetic cell sorter. The magnetized column retains the unwantedcells and the resting B cells are collected in the flow-through.Purified B-cells are stimulated with lipopolysaccharide or an anti-CD40antibody and interleukin 4. Stimulated B-cells are treated with vehiclealone or with PI3K6 inhibitors of the present invention such as compound53 with and without mTOR inhibitors such as rapamycin, rapalogs, ormTORC1/C2 inhibitors. The results are expected to show that in thepresence of mTOR inhibitors (e.g., rapamycin) alone, there is little tono substantial effect on IgG and IgE response. However, in the presenceof PI3K6 and mTOR inhibitors, the B-cells are expected to exhibit adecreased IgG response as compared to the B-cells treated with vehiclealone, and the B-cells are expected to exhibit a decreased IgE responseas compared to the response from B-cells treated with PI3K6 inhibitorsalone.

(b) TNP Assay

Mice are immunized with TNP-Ficoll or TNP-KHL and treated with: vehicle,a PI3Kδ inhibitor, for example, compound 53 of the present invention, anmTOR inhibitor, for example rapamycin, or a PI3Kδ inhibitor incombination with an mTOR inhibitor such as rapamycin. Antigen-specificserum IgE is measured by ELISA using TNP-BSA coated plates and isotypespecific labeled antibodies. It is expected that mice treated with anmTOR inhibitor alone exhibit little or no substantial effect on antigenspecific IgG3 response and no statistically significant elevation in IgEresponse as compared to the vehicle control. It is also expected thatmice treated with both PI3K6 inhibitor and mTOR inhibitor exhibit areduction in antigen specific IgG3 response as compared to the micetreated with vehicle alone. Additionally, the mice treated with bothPI3Kδ inhibitor and mTOR inhibitor exhibit a decrease in IgE response ascompared to the mice treated with PI3Kδ inhibitor alone.

(c) Rat Collagen Induced Arthritis Model

Female Lewis rats are anesthetized and given collagen injectionsprepared and administered as described previously on day 0. On day 6,animals are anesthetized and given a second collagen injection. Calipermeasurements of normal (pre-disease) right and left ankle joints areperformed on day 9. On days 10-11, arthritis typically occurs and ratsare randomized into treatment groups. Randomization is performed afterankle joint swelling is obviously established and there is good evidenceof bilateral disease.

After an animal is selected for enrollment in the study, treatment isinitiated. Animals are given vehicle, PI3Kδ inhibitor, or PI3Kδinhibitor in combination with rapamycin. Dosing is administered on days1-6. Rats are weighed on days 1-7 following establishment of arthritisand caliper measurements of ankles taken every day. Final body weightsare taken on day 7 and animals are euthanized.

It is expected that the combination treatment using PI3Kδ inhibitor andrapamycin provides greater efficacy than treatment with PI3K6 inhibitoralone.
